Synopsis

Low pressure will develop along a stalled front S of the area Sun, then lift NE across the outer portions later Sun into Mon. A strong cold front will move SE across the waters Mon into early Mon night. The aforementioned low will then become absorbed into a deeper, broadening low near the Gulf of Saint Lawrence Mon and Mon night. High pressure will build E into the waters behind the front Tue and Tue night as the low deepens well N of the area. The high will drift E across the waters Wed, then clear E of the area Wed night while maintaining a ridge across the waters through Thu night.
